“Well, I started going to class years ago with a teacher named Mark Blanchard, who has taught Jennifer Lopez,” she begins during Mohegan Sun’s Reality Check event in Uncasville, Conn. “I started thinking ‘this is all baloney—yoga; how can this really be doing anything?’ And my body completely changed. My arms are completely different. I was more narrow.”

She continues, “It changed my body, but more importantly, mentally, it helped me, because I suffer from anxiety.”

“It also helps me to say ‘slow down,’” she says. “Even my movements, [my teacher] Mark was like ‘you’re always so fast, fast, fast—moving—with your kids, your work, your husband. You need to slow down with everything you do. Even your movements—when I tell you to move to this move to that move, you jerk. Everything you do needs to be slower.’ That gave me confidence to slow down. I close my eyes, and he forces me to realize how high-strung I have to be in order to be doing all this stuff that I’m juggling all the time.”

Kyle discovered power yoga was the key to keeping calm after going without it.

“When I first started doing yoga again, I called Mark up after many years of a break from yoga—after I got pregnant with Portia [six years ago], I think, was my last class,” she says. “He started coming to my house more to help me relax mentally, and my body started changing again. I was like ‘thank God.’ I don’t ever want to give it up now.”

“Every other class seems so easy after doing Mark’s power yoga,” she says. “For me, regular yoga can be slow and easy. I found other classes being way too easy after doing his class. I mean, he has me doing things that make me look like I’m doing Cirque du Soleil sometimes! [laughs]”
